ALCAN trails

So I'm probably driving from Alaska to Seattle in August, should be prime riding season still, and other than Whitehorse I just don't know what is on the way down south as far as trail systems. Doesn't have to be directly accessed from the ALCAN but ideally less than a 2-3 hour diversion to get to trails would improve my stoke for a long solo drive.

Carcross, YT a little out of the way but good riding. Talk with some of the White Horse folks usually a bunch go down, and a few tours leave from White Horse for day trips.http://www.montanamountain.ca/
